Shell Script writing

[radocool]

Hello all,
I am trying to make my Starcraft work via a shell script.I have an iso image of the expansion Brood War and i want to do the following:
1. Mount the broodwar iso image to, let's say, /media/iso
2.Starting the game with wine
3.After exiting starcraft, unmount the broodwar image

My script looks like this;
#!/bin/bash
# My Starcraft Script
cd /home/user/Starcraft
sudo -p xxxxxxxxx mount -o loop broodwar.iso /media/iso
wine /home/user/games/Starcraft/starcraft.exe

My particular problem is the implementation of th third step.If someone knows how to do it, please help me, because I'm still new to shell scripting.
With kind regards,
Rado

#!/bin/bash
# My Starcraft Script
cd /home/user/Starcraft
sudo -p xxxxxxxxx mount -o loop broodwar.iso /media/iso
wine /home/user/games/Starcraft/starcraft.exe
sudo -p xxxxxxxxx umount /media/iso

the script will sit there waiting for starcraft to exit. When it does the script will go onto the next step and unmount the CD

huw-l is correct, but if I may suggest an additional improvement.

As root enter the following new line into /etc/fstab
/home/user/Starcraft/broodwar.iso /mnt/iso loop,user 0 0

This line permits any user to mount and unmount the iso image as a loop device at the mountpoint /mnt/iso. (Note - that user may need access permission on the .mnt/iso directory and to the iso image). So then your sudo -p ... portions of the command go away and your script lools like ....

#!/bin/bash
# My Starcraft Script
cd /home/user/Starcraft
mount broodwar.iso
wine /home/user/games/Starcraft/starcraft.exe
umount broodwar.iso

Can you point me to a good page that tells the basics for creating scripts?

Firewing1 has a link to a very nice document.

If you want to see examples of shell scripts, look in (or grep through) /etc/init.d/*
These are the system services startup scripts and there are examples of almost every feature and quoting style for scripts. Some are very simple - others quite complex.

Also, if you want to start scripting, a nice way to start is to make Nautilus scripts. Google it for more info, you'll see how they work.
